                                 requirements of the Exemption.

                                 The Exemption may cover the acquisition and

                                 the Offered Certificates. Moreover, each Plan
                                 fiduciary should determine whether under the

                          PRELIMINARY SUMMARY OF TERMS

Shifting Interest in             Additional credit enhancement is provided by
Prepayments:                     the allocation, subject to certain exceptions,
                                 of all principal prepayments and certain
                                 liquidation proceeds on the mortgage loans in a
                                 loan group to reduce the principal amount of
                                 the Class A Certificates of the related group
                                 during the first seven years after the closing
                                 date. In addition, a reduced, but still
                                 disproportionately large, allocation of these
                                 principal collections to reduce the principal
                                 amount of those Class A Certificates will occur
                                 during the eighth through eleventh years
                                 following the closing date. The
                                 disproportionate allocation of prepayments and
                                 certain liquidation proceeds on the mortgage
                                 loans in a loan group will accelerate the
                                 amortization of the related Class A
                                 Certificates relative to the amortization of
                                 the subordinate certificates. As a result, it
                                 is more likely that the credit support
                                 percentage for the Class A Certificates of a
                                 group will be maintained and may be increased
                                 during the first eleven years. (Please see the
                                 "Senior Prepayment Percentage" section below.)

Interest Accrual:                Interest will accrue on the Offered
                                 Certificates during each one-month period
                                 ending on the last day of the month preceding
                                 the month in which each Distribution Date
                                 occurs. The initial interest accrual period
                                 will be deemed to have commenced on February 1,
                                 2006. Interest that accrues on such class of
                                 Certificates during an interest accrual period
                                 will be calculated on the assumption that
                                 distributions that reduce the class balances
                                 thereof on the Distribution Date in that
                                 interest accrual period are made on the first
                                 day of the interest accrual period. Interest
                                 will be calculated on the basis of a 360-day
                                 year consisting of twelve 30-day months.

                                      The amount of interest that will accrue on
                                 your Certificates during each interest accrual
                                 period is equal to:

                                      (a) one-twelfth of the pass-through rate
                                 for your class multiplied by the principal
                                 balance of your Certificate on the Distribution
                                 Date, minus

                                      (b) the amount allocated to your class of
                                 certain interest shortfalls arising from the
                                 timing of prepayments on the Mortgage Loans,
                                 interest limitations applicable to certain
                                 military or similar personnel and interest
                                 losses allocated to your class. (See Disclosure

                                                                              14

                                 will accrue on the Stated Principal Balance of
                                 each Mortgage Loan at a rate (the
                                 "Administrative Fee Rate") equal to the sum of
                                 the Servicing Fee Rate for such Mortgage Loan
                                 and the Master Servicing Fee Rate. The "Trustee

Compensating Interest:           The aggregate Servicing Fee payable to a
                                 Servicer for any month will be reduced by an
                                 amount equal to the lesser of (i) the

                                 Distribution Date and (ii) one-twelfth of

                                 Loans. Such amounts will be used to cover full

Net Mortgage Interest Rate:      As to any Mortgage Loan and Distribution Date,
                                 the excess of its mortgage interest rate over
                                 the Administrative Fee Rate.

                           PRELIMINARY CREDIT SUPPORT

The Class B Certificates provide credit support for Class A Certificates. In
addition, under certain circumstances principal otherwise payable to the Class B
Certificates will be paid to the Class A Certificates. Please see the diagram
below. Additional credit enhancement is provided by the allocation of all
principal prepayments and certain liquidation proceeds to the Class A
Certificates, subject to certain exceptions, for the first seven years and the
disproportionately greater allocation of prepayments to the Class A Certificates
over the following four years. The disproportionate allocation of prepayments
will accelerate the amortization of the Class A Certificates relative to the
amortization of the Subordinate Certificates. As a result, the credit support
percentage for the Class A Certificates should be maintained and may be
increased during the first eleven years.

                           GROUP 1 COLLATERAL SUMMARY

DESCRIPTION OF THE MORTGAGE LOANS

The Group 1 Mortgage Loans consist of 3/1 One-Year LIBOR based ARMs secured by
first lien, one-to-four family residential properties. The Mortgage Loans have a
fixed interest rate for the first 3 years after origination and thereafter the
Mortgage Loans have a variable interest rate. Approximately 69.77% of the Group
1 Mortgage Loans require only the payment of interest until the 37th payment.
The mortgage interest rate adjusts at the end of the initial fixed interest rate
period and annually thereafter. The mortgage interest rates will be indexed to
One-Year LIBOR and will adjust to that index plus a certain number of basis
points (the "Gross Margin"). The One-Year LIBOR index will be equal to the rate
quoted as of either (i) the first business day of the month preceding the
adjustment date or (ii) forty-five days prior to the adjustment date. The
One-Year LIBOR Index is the average of the interbank offered rates for one-year
U.S. dollar-denominated deposits in the London Market ("LIBOR") as published in
The Wall Street Journal. The mortgage interest rates are subject to lifetime
maximum mortgage interest rates, which range from 10.000% to 12.875%. The
effective minimum interest rate for substantially all of the Mortgage Loans will
be each Mortgage Loan's respective Gross Margin.

Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at
any time without penalty.

The approximate collateral statistics for the Mortgage Loans are listed below as
of the Cut-off Date. The balances and percentages may not be exact due to
rounding.

                           GROUP 2 COLLATERAL SUMMARY

DESCRIPTION OF THE MORTGAGE LOANS

The Group 2 Mortgage Loans consist of 5/1 One-Year LIBOR based ARMs secured by
first lien, one-to-four family residential properties. The Mortgage Loans have a
fixed interest rate for the first 5 years after origination and thereafter the
Mortgage Loans have a variable interest rate. Approximately 65.25% of the Group
2 Mortgage Loans require only the payment of interest until the 61st payment.
The mortgage interest rate adjusts at the end of the initial fixed interest rate
period and annually thereafter. The mortgage interest rates will be indexed to
One-Year LIBOR and will adjust to that index plus a certain number of basis
points (the "Gross Margin"). The One-Year LIBOR index will be equal to the rate
quoted as of either (i) the first business day of the month preceding the
adjustment date or (ii) forty-five days prior to the adjustment date. The
One-Year LIBOR Index is the average of the interbank offered rates for one-year
U.S. dollar-denominated deposits in the London Market ("LIBOR") as published in
The Wall Street Journal. The mortgage interest rates are subject to lifetime
maximum mortgage interest rates, which range from 9.625% to 12.250%. The
effective minimum interest rate for substantially all of the Mortgage Loans will
be each Mortgage Loan's respective Gross Margin.

Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at
any time without penalty.

The approximate collateral statistics for the Mortgage Loans are listed below as
of the Cut-off Date. The balances and percentages may not be exact due to
rounding.

                           GROUP 3 COLLATERAL SUMMARY

DESCRIPTION OF THE MORTGAGE LOANS

The Group 3 Mortgage Loans consist of 7/1 One-Year LIBOR based ARMs secured by
first lien, one-to-four family residential properties. The Mortgage Loans have a
fixed interest rate for the first 7 years after origination and thereafter the
Mortgage Loans have a variable interest rate. Approximately 48.17% of the Group
3 Mortgage Loans require only the payment of interest until the 85st payment.
The mortgage interest rate adjusts at the end of the initial fixed interest rate
period and annually thereafter. The mortgage interest rates will be indexed to
One-Year LIBOR and will adjust to that index plus a certain number of basis
points (the "Gross Margin"). The One-Year LIBOR index will be equal to the rate
quoted as of either (i) the first business day of the month preceding the
adjustment date or (ii) forty-five days prior to the adjustment date. The
One-Year LIBOR Index is the average of the interbank offered rates for one-year
U.S. dollar-denominated deposits in the London Market ("LIBOR") as published in
The Wall Street Journal. The mortgage interest rates are subject to lifetime
maximum mortgage interest rates, which range from 10.000% to 11.750%. The
effective minimum interest rate for substantially all of the Mortgage Loans will
be each Mortgage Loan's respective Gross Margin.

Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at
any time without penalty.

The approximate collateral statistics for the Mortgage Loans are listed below as
of the Cut-off Date. The balances and percentages may not be exact due to
rounding.

                           GROUP 4 COLLATERAL SUMMARY

DESCRIPTION OF THE MORTGAGE LOANS

The Group 4 Mortgage Loans consist of 3/1 One-Year LIBOR based ARMs secured by
first lien, one-to-four family residential properties. The Mortgage Loans have a
fixed interest rate for the first 3 years after origination and thereafter the
Mortgage Loans have a variable interest rate. Approximately 93.64% of the Group
4 Mortgage Loans require only the payment of interest until the 37th payment.
The mortgage interest rate adjusts at the end of the initial fixed interest rate
period and annually thereafter. The mortgage interest rates will be indexed to
One-Year LIBOR and will adjust to that index plus a certain number of basis
points (the "Gross Margin"). The One-Year LIBOR index will be equal to the rate
quoted as of either (i) the first business day of the month preceding the
adjustment date or (ii) forty-five days prior to the adjustment date. The
One-Year LIBOR Index is the average of the interbank offered rates for one-year
U.S. dollar-denominated deposits in the London Market ("LIBOR") as published in
The Wall Street Journal. The mortgage interest rates are subject to lifetime
maximum mortgage interest rates, which range from 10.500% to 13.500%. The
effective minimum interest rate for substantially all of the Mortgage Loans will
be each Mortgage Loan's respective Gross Margin.

Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at
any time without penalty.

The approximate collateral statistics for the Mortgage Loans are listed below as
of the Cut-off Date. The balances and percentages may not be exact due to
rounding.

                           GROUP 5 COLLATERAL SUMMARY

DESCRIPTION OF THE MORTGAGE LOANS

The Group 5 Mortgage Loans consist of 5/1 One-Year LIBOR based ARMs secured by
first lien, one-to-four family residential properties. All but one of the
Mortgage Loans have a fixed interest rate for the first 5 years after
origination and thereafter the Mortgage Loans have a variable interest rate.
Approximately 75.47% of the Group 5 Mortgage Loans require only the payment of
interest until the 61st payment. The mortgage interest rate adjusts at the end
of the initial fixed interest rate period and annually thereafter. The mortgage
interest rates will be indexed to One-Year LIBOR and will adjust to that index
plus a certain number of basis points (the "Gross Margin"). The One-Year LIBOR
index will be equal to the rate quoted as of either (i) the first business day
of the month preceding the adjustment date or (ii) forty-five days prior to the
adjustment date. The One-Year LIBOR Index is the average of the interbank
offered rates for one-year U.S. dollar-denominated deposits in the London Market
("LIBOR") as published in The Wall Street Journal. The mortgage interest rates
are subject to lifetime maximum mortgage interest rates, which range from 9.625%
to 12.625%. The effective minimum interest rate for substantially all of the
Mortgage Loans will be each Mortgage Loan's respective Gross Margin.

Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at
any time without penalty.

The approximate collateral statistics for the Mortgage Loans are listed below as
of the Cut-off Date. The balances and percentages may not be exact due to
rounding.

                           GROUP 6 COLLATERAL SUMMARY

DESCRIPTION OF THE MORTGAGE LOANS

The Group 6 Mortgage Loans consist of 7/1 One-Year LIBOR based ARMs secured by
first lien, one-to-four family residential properties. The Mortgage Loans have a
fixed interest rate for the first 7 years after origination and thereafter the
Mortgage Loans have a variable interest rate. Approximately 86.81% of the Group
6 Mortgage Loans require only the payment of interest until the 85th payment.
The mortgage interest rate adjusts at the end of the initial fixed interest rate
period and annually thereafter. The mortgage interest rates will be indexed to
One-Year LIBOR and will adjust to that index plus a certain number of basis
points (the "Gross Margin"). The One-Year LIBOR index will be equal to the rate
quoted as of either (i) the first business day of the month preceding the
adjustment date or (ii) forty-five days prior to the adjustment date. The
One-Year LIBOR Index is the average of the interbank offered rates for one-year
U.S. dollar-denominated deposits in the London Market ("LIBOR") as published in
The Wall Street Journal. The mortgage interest rates are subject to lifetime
maximum mortgage interest rates, which range from 10.500% to 11.750%. The
effective minimum interest rate for substantially all of the Mortgage Loans will
be each Mortgage Loan's respective Gross Margin.

Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at
any time without penalty.

The approximate collateral statistics for the Mortgage Loans are listed below as
of the Cut-off Date. The balances and percentages may not be exact due to
rounding.

                           GROUP 7 COLLATERAL SUMMARY

DESCRIPTION OF THE MORTGAGE LOANS

The Group 7 Mortgage Loans consist of 10/1 One-Year LIBOR based ARMs secured by
first lien, one-to-four family residential properties. The Mortgage Loans have a
fixed interest rate for the first 10 years after origination and thereafter the
Mortgage Loans have a variable interest rate. Approximately 98.78% of the Group
7 Mortgage Loans require only the payment of interest until the 121st payment.
The mortgage interest rate adjusts at the end of the initial fixed interest rate
period and annually thereafter. The mortgage interest rates will be indexed to
One-Year LIBOR and will adjust to that index plus a certain number of basis
points (the "Gross Margin"). The One-Year LIBOR index will be equal to the rate
quoted as of either (i) the first business day of the month preceding the
adjustment date or (ii) forty-five days prior to the adjustment date. The
One-Year LIBOR Index is the average of the interbank offered rates for one-year
U.S. dollar-denominated deposits in the London Market ("LIBOR") as published in
The Wall Street Journal. The mortgage interest rates are subject to lifetime
maximum mortgage interest rates, which range from 10.250% to 11.750%. The
effective minimum interest rate for substantially all of the Mortgage Loans will
be each Mortgage Loan's respective Gross Margin.

Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at
any time without penalty.

The approximate collateral statistics for the Mortgage Loans are listed below as
of the Cut-off Date. The balances and percentages may not be exact due to
rounding.

                       AGGREGATE GROUP COLLATERAL SUMMARY

DESCRIPTION OF THE MORTGAGE LOANS

The Aggregate Group Mortgage Loans consist of 3/1, 5/1, 7/1, and 10/1 One-Year
LIBOR based ARMs secured by first lien, one-to-four family residential
properties. The Mortgage Loans have a fixed interest rate for the first 3, 5, 7,
and 10 years, respectively, after origination and thereafter the Mortgage Loans
have a variable interest rate. Approximately 75.69% of the Aggregate Group
Mortgage Loans require only the payment of interest until the 37th, 61st, 85th,
or 121st payment. The mortgage interest rate adjusts at the end of the initial
fixed interest rate period and annually thereafter. The mortgage interest rates
will be indexed to One-Year LIBOR and will adjust to that index plus a certain
number of basis points (the "Gross Margin"). The One-Year LIBOR index will be
equal to the rate quoted as of either (i) the first business day of the month
preceding the adjustment date or (ii) forty-five days prior to the adjustment
date. The One-Year LIBOR Index is the average of the interbank offered rates for
one-year U.S. dollar-denominated deposits in the London Market ("LIBOR") as
published in The Wall Street Journal. The mortgage interest rates are subject to
lifetime maximum mortgage interest rates, which range from 9.625% to 13.500%.
The effective minimum interest rate for substantially all of the Mortgage Loans
will be each Mortgage Loan's respective Gross Margin.

Borrowers are permitted to prepay their Mortgage Loans, in whole or in part, at
any time without penalty.

The approximate collateral statistics for the Mortgage Loans are listed below as
of the Cut-off Date. The balances and percentages may not be exact due to
rounding.
